J'OHNJ'. HALLIWELL, OF TUCKAHOE, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO R. HOE AND CO., INC., OF NEW YORK, N. TY., A CORPORATION OF NEW YORK INKING MECBANISM This invention relates to certain improvements 1n inklng mechanlsm for prlntmg ma# chines.

Inking mechanism for printing machines.

usually include an ink distributing cylinder or distributor to which ink is de ivered in various ways.` Cooperating with this dis.

tributor delivering the ink .to the form memberofthe printing couple, usually through themedium of small rolls known as form rolls. To effect a good distribution of the ink on the distributor, a number of inking rolls have been employed. These inking rollsare small and to get a desired number have to be placed pretty close together. Ithas been customary v to vibrate certain of these rolls, that is, a

means is providedv to effect a longitudinal movement of these rolls relatively to the distributor. It-has been diicult, owing to the necessary close adjacency of these small rolls to vibrate them all, as it has been difficult to get the necessary partsv for effecting the vibration in the-small space provided.-

It is the especial object of the present -invention to provide an inking mechanism in which the small distributing rolls may b e arranged closely adjacent so as" to provide a good distribution of ink, and in which any or all of these small rolls may be vibrated, and a mechanism in which'the ink distributing cylinder or'drum itself is also vibra-ted,

' the vibrationl ofthe drum and certain of the rolls being in opposite directions, so that a yery good distribution of the ink is effected.

A further object ofthe invention is to provide a construction-by which this may be effected by a single cam, and in which the parts are few in number and thus simple to construct.

With these and other objects not specifically referred to, the invention consists in certain novel parts, arrangements and combinations which will be described in connection..

with the-accompanying drawings, in which Figure 1 is an end vlew, partly in section and partly broken away, of the improved inking mechanism;

Figure 2 isa partial side view of the conl struction shown in Fig. 1, the view being partly in section and certain parts being omitted for the sake. of clearness;

Figure 3 is a detail view on an enlarged' scale, the view being taken on the irregular line 3-3 of Fig. .1, looking in the direction of. the arrow, showing the parts arranged' outside the press frame, and

Figure 4 is a detail view on an enlarged scale, the view being taken on the line 4-4 of F ig'. 1, looking in the direction of the arrow, showing the arrangement of the parts which are located inside the press frame.

Referring now to these drawings, 1 indicates theframing of the machine, which may be ofany usual or desired configuration, for supporting the parts. Mounted in this framing on a shaft 2 is one member of a printing couple, shown in the form of a cylinder 3, th1s cylinder being driven in any suitable manner, not shown. Cooperating with this cylinder are a pair of the usual form rolls 4, 5 supported on shafts 6, 7 suitably mounted frames 1. From the pump box ink isv delivy ered through pipes, one of which is shown marked 11, to an ink rail 12 which delivers the ink to the surface of the cylinder. Co.- operating with the cylinder are a'plurality of ink distributing rolls marked 13, 14, 15, 16v

and 17, the rolls 13, 1/1 and 15 being carried ons'hafts 18, 19 and 20 suitably supported, and the rolls 16, 17 being'supported by shafts 21 22. W.

ln accordance with the invention, the ink distributing drum 8 and the ink distributing rolls are vibrated, andthis vibration lis effected so that the vibration of the drum is in an i opposite direction td that of certainof the rolls. Furthermore, thesmalll rolls arelpreferably vibrated so that the time of vibration is different for certain of the rolls, a very good distribution of the ink being effected by thi@ arrangement.

5- In the best constructions, furthermore, the

vibration of the parts is effected by a single cam. While the. s ecific construction for effecting this may he somewhat varied, i-n the articular construction shown, the ink distributing cylinder 8 is supported by a air of heads, one of which is shown marke 23, this head being secured to the cylinder in any suitable manner, as by bolts 24. This head 23 has a short shaft 25 which is journaled in the side frame 1, before referred to, this shaft extendinfr through the frame, as shown in Fig. 2. l\ ounted on this shaft and having a longitudinal movement therewith is an operatin cam 26 having a cam groove vAs shown (see F ig. 4)

27, this cam ing located inside the side frames 1, before referred to. Cooperating with this cam is a cam roll 28 mounted .in the end of a bracket arm 29 fixedly secured to one of the side frames. As the cam rotates the distributing cylinder 8 is thus given a to and fro vibrating movement.

In the particular construction illustrated,

all the small rolls are also given a vibrating movement and this vibrating movement as to certain of the rolls i's in a direction opposite to that of the distributor 8. While this may be effected in various Ways, in the particular construct-ion shown, two .of the small rolls, as 13 and 15, are operated by connections positioned outside the framing of the machine. As shown, the end of the shaft 25, beyond the fra-mes, is rovided with a grooved collar or sleeve 30 Exedly secured on the shaft. Working in the groove of this collar are rolls 31, 32 carried on the inner ends of rocker arms '33, 34 pivoted on a stud 35 carried in a bracket 36 secured to the side frame of the machine. The arms 33, 34 carry at their other ends rolls 37, 38 which run in grooves 39 on sleeves 40 fast on the ends o f the roll shaft 18, 20, before referred to. Thus, as the operatm cam 26 is shifted' sidewise bythe roll 28, t e shaft 25 is given a sidewise movement and through the arms 33, 34 the rolls 13, 15 are given a vibratory movement, this movement being in a direction opposite to that imparted to the vibrating cylinder 8.

The roll 14 isalso, in the particular construction illustrated, given a vibrating movement. This is effected through'- the cam 26.

rocker arm 41 pivoted on a studV 42 in a bracket 43 'secured Vto the inside of the side frame 1, before referred to. This arm atone end has a roll 44 which works in the groove 27 of the cam 26, before referred to, and this Y arm at its other end carries a roll 45 running 1n a groove 46 in a sleeve 47'on the end of the roll shaft.

In the construction illustrated, the rolls 16,

there is provided a 17 are also vibrated and, in the particular construction illustrated, one of these rolls, as the roll 17, is vibrated from the cam 27, and the other roll 16 is vibrated from the roll 17 and in the opposite direction thereto. While the construction for effecting this may be somewhat varied, in the particular construction illustrated, see dotted lines in Fig. 1, there is provided a rocker arm 48 pivoted on a stud 49 mounted in a bracket 50 secured to the frame of the machine. This rocker armI 48, at one end, has a roll 51 running in the groove 27 of the cam 26, and this rocker arm at its other end has a roll 52 running in a grooved collar 53, on the end of the roll shaft or journal 22. Also running in the groove of this collar, is aroll 54 on a rocker arm 55 pivoted on a stud 56 in a bracket 57 secured in the side frame of the machine, this arm at its other end carrying a roll 58 running in a grooved collar 59 on the end of the roll shaft or journal 21.

Vith this construction it will be observed that the parts operated by ,the cam 27 are vibrated at different times, owing tothe position of the operating rolls Iin the cam' groove, and certain of the small rolls are vibrated in a direction opposite to the direction of the drum 8. Vith this construction, therefore, a seesaw action is produced and a very efficient grinding and distribution of the ink on the distributor roll is effected. Furthermore, it will be observed that at no time are all of the small rolls stationary withrespect to the distributor, the parts being so timed that as certain of the rolls stop at the end of their reciprocating movement other of the rolls are still being reciprocated.

Thus in the particular arrangement shown the rolls 13 and 15 vibrate in time with the distributor 8 but in opposite directions there to; the roll- 17 moves in the opposite direction to the distributor 8 but out of time therewith the roll 16 moves in time with but in the opposite direction to the roll 17,` and the roll 14 moves lin the opposite direction to the distributor 8` but out of time therewith and out of time with the roll 17. Thus while the distributor 8 and therolls 13 and 15 are dwelling at the end of their stroke, the other rolls are in vibratory motion.

The parts may be driven in any suitable or desired manner. In the particular construction illustrated, the parts are driven from the form cylinder 3. To effect this, the shaft of the form cylinder carries a gear 60 which is in mesh with an intermediate gear 61. Thisntermediategearl is in mesh with a large gear 62, on the opposite end of the drum 8 to that shown in Fig. 2, and drives the drum. The short shaft 25 has, at its outer end beyond the frame of the machine, a gear 63 keyed thereon. This gear 63 is in mesh with a wide gear 64 fast on a stud 65. This a beveled gearv 7 0 in mesh with a beveled gear 71 on the stud 65, before referred to.

With the construction shown and described, a very'efiicient distribution of the ink is obtained on the distributor, While the invention has been shown and described in its preferred form, it Will be understood that variouschanges maybe made in its specific construction and operating mechanism of the f parts Without departing from the invention, asv defined in the appended claims.
